Seminar by Katia Colaneri in Milan (25.01.23)
by Valeria Bignozzi 23 May '23

23 May '23

Dear all, you're invited to the seminar that will take place, in hybrid mode, at the Department of Statistics and Quantitative Methods, University of Milano-Bicocca. More details: • Speaker: Katia Colaneri (email: katia.colaneri(a)uniroma2.it <mailto:katia.colaneri@uniroma2.it>) Title: Some Optimisation Problems in Insurance with a Terminal Distribution Constraint Abstract: In this paper, we study two optimisation settings for an insurance company, under the constraint that the terminal surplus at a deterministic and finite time T follows a normal distribution with a given mean and a given variance. In both cases, the surplus of the insurance company is assumed to follow a Brownian motion with drift. First, we allow the insurance company to pay dividends and seek to maximise the expected discounted dividend payments or to minimise the ruin probability under the terminal distribution constraint. Here, we find explicit expressions for the optimal strategies in both cases, when the dividend strategy is updated at discrete points in time and continuously in time. Second, we let the insurance company buy a reinsurance contract for a pool of insured or a branch of business. We only allow for piecewise constant reinsurance strategies producing a normally distributed terminal surplus, whose mean and variance lead to a given Value at Risk or Expected Shortfall at some confidence level α. We investigate the question which admissible reinsurance strategy produces a smaller ruin probability, if the ruin-checks are due at discrete deterministic points in time. This presentation is based on a joint work with Julia Eisenberg (TU Vienna) and Benedetta Salterini (University of Firenze) Seminar venue: University of Milano-Bicocca Department of Statistics and Quantitative Methods Aula Seminari 4026, 4th floor, Building U7 January 25th, 4:30 pm Webex Link : https://unimib.webex.com/unimib/j.php?MTID=m40cd4bb0d7bb8035ca68f3821f453b33 <https://unimib.webex.com/unimib/j.php?MTID=m40cd4bb0d7bb8035ca68f3821f453b33> Join by meeting number Meeting number (access code): 2743 983 3965 Meeting password: c2uJfPBVe83 (22853728 from phones) Best regards, Valeria

Corso di dottorato di Amine Asselah in Sapienza
by Lorenzo Taggi 22 May '23

22 May '23

Si annuncia il corso di dottorato su *Random Walks e Branching Random Walks* del professor Amine Asselah (università di Parigi-Est Créteil) presso il dipartimento di Matematica di Sapienza Università di Roma. Si riportano l’abstract e il calendario, in allegato il programma dettagliato. Si prega di diffondere l’annuncio a possibili interessati. Per essere inseriti nella mailing list del corso e essere aggiornati su possibili variazioni del calendario si prega di inviare un'email a lorenzo.taggi(a)uniroma1.it *ABSTRACT:* Simple Random Walk is the first example of a Markovian process, whereas Branching Random Walk has a time indexed by a random tree, and looses the SRW’s sequential way of visiting space. The highlights of the course would be two phenomena in high dimensions linked with folding. - The chances that two independent walks meet for a long time. - The chances that two independent branching walks both visit a large region, and this is to be discovered during the course. We plan to have self-contained lectures (with little pre-requisites), and will start with reviewing useful facts (classical and not) on random walks. *CALENDARIO:* Tutte le lezioni hanno luogo dalle 11:00 alle 13:00 presso il dipartimento di Matematica in aula B nei seguenti giorni: Lez. 1: lunedì 29/5 Lez. 2: giovedì 1/6 Lez. 3: giovedì 8/6 Lez. 4: venerdì 9/6 Lez. 5: lunedì 12/6 Lez. 6: giovedì 15/6 Lez. 7: lunedì 19/6 Lez. 8: giovedì 22/6

seminario Francois Baccelli 24 maggio
by Daniela De Canditiis 21 May '23

21 May '23

Buongiorno a tutti, il prossimo appuntamento del ciclo Seminari generali IAC si terrà Mercoledì 24 Maggio ore 14:30 sul Canale Youtube Cnr-IAC al link https://www.youtube.com/watch?v=JgsmwZg7eAg con Francois Baccelli Title High dimensional stochastic geometry in the Shannon regime Abstract This talk will focus on Euclidean stochastic geometry in the Shannon regime. In this regime, the dimension n of space tends to infinity, point processes have intensities which are exponential functions of n, and the random compact sets have diameters of order square root of n. Three basic models of stochastic geometry based on Poisson processes will be considered: the Boolean model, the Poisson-Voronoi tessellation and the Poisson hyperplane tessellation. We will show how to calculate the asymptotic behavior of the classical quantities of stochastic geometry for these three models in the Shannon regime: for the Boolean model, the volume fraction, the percolation threshold or the size of the connected components; for tessellations, statistics of geometric properties of cells (volume, diameter, etc.). These questions are motivated by problems in information theory, including the calculation of error exponents for channel coding based on random codes and calculating the distortion in the one-bit compression-based source coding. Survey of work in collaboration with Venkat Anantharam (UC Berkeley) and Eliza O'Reilly (Caltech).

SPASS Seminar: Francesco Russo
by Andrea Agazzi 19 May '23

19 May '23

Dear Colleagues, We would like to invite you to the following SPASS <https://sites.google.com/unipi.it/spass> seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *Semimartingales with jumps, weak Dirichlet processes and path-dependent martingale problems* by *Francesco Russo* (ENSTA-Paris) The seminar will take place on *TUE, 23.05.2023* at *14:00 CET* in Aula Seminari, Department of Mathematics, University of Pisa and streamed online here <https://meet.google.com/gji-phwo-vbg>. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass -------------------------------------------- *Abstract: In this talk we will revisit the notion of weak Dirichlet process which is the natural extension of semimartingale with jumps. If X is such a process, then it is the sum of a local martingale M and a martingale ortogonal process A in the sense that [A, N] = 0 for every continuous local martingale N . We remark that if [A] = 0 then X is a Dirichlet process. The notion of Dirichlet process is not very suitable in the jump case since in this case A is forced to be continuous.The talk will discuss the following points.1. To provide a (unique) decomposition which is also new for semimartingales with jumps.2. To discuss some new stability theorem for weak Dirichlet processes through C^{0,1} transformations.3. To discuss various examples of such processes arising from path-dependent martingale problems. This includes path-dependent stochastic differential equations involving a distributional drift and with jumps.The talk is based on a joint paper with E. Bandini (Bologna).*
